Both models are equipped with a top scale for direct readings on the top of the capsule at the lubber line. They have sapphire jewel bearing for friction-free movement of the card, allowing fast and accurate readings.

Accuracy: Max ±0.5° from true magnetic course with precision sighting.
Max ±1.0° from true magnetic course with direct reading at the lubber line on top of the capsule.

Clinometer card: The ClinoMaster Lensatic is equipped with an aluminium clinometer card with precision scale and the ClinoMaster Prismatic is equipped with a transparent clinometer card with precision scale.
